Review Image by Andrea Doesn't Know
I love this clock. It is super simple to set up and use. The numbers are big and bright for those bleary mornings. The alarm is loud, I only have to set it on volume 2 so this thing will wake the neighbors up if you are a hard to rouse type. The best part are the many different colors you can set the numbers to be. There are even rainbow changing colors. I change the color everyday just because. Keep in mind it has a place for batteries so that it remembers it's place in case outage. I keep forgetting to put them in. Make waking up a little more fun. Great deal for the price. ... show more

    • My daughters love this clock
Color: Pink+rgb
Great quality and perfect alarm clock! I bought it for when my kids are grounded from their phones. Turns out the kids prefer the clock so I need to buy one for each! You can change the font, colors, brightness, the noise levels also adjust to super loud which is perfect for my heavy sleepers!

    • Great alarm clock for price
Color: White+rgb
I love this alarm clock! So many different color options and is extremely loud which is perfect for heavy sleepers like myself. You can set two alarms and there is a snooze option. There is also an option to dim the lights so when you’re sleeping it’s not overwhelmingly bright. There is a light on the snooze button on top that you can change the color of as well. Great value for price in my opinion. ... show more

The cons: (1) The controls are on the back, so when I grip the clock to change the alarm settings, it is too easy to accidentally change other settings. (2) The USB cable juts out in the back. It is not snug and wiggles, so the display can be intermittent. There is no strain relief on the cable. Good design would mean setting up the USB port sideways so that the cable slips sideways, along with a couple of notches to prevent strain on the cable. It would also allow the clock to be placed flush with the background, if that’s what the user wishes. (3) The light on top is nice, except that it is a single cycles through all the lights. Say I want the red light on, I have to cycle through white, blue, green, magenta, then red. That’s 5 clicks. Then to turn it off, I have to cycle through yellow, cyan, then off. That’s 3 clicks. This means that each time I turn the light on or off, instead of going thru 2 clicks, I have to go through 8 clicks—and count along the way. That’s 4 times more wear and tear on the button. (4) Too much flipping from front and back to set the alarm. Here’s how it goes: - click TOP alarm button - long-click TOP button for the hour to flash - look at BACK to locate + or – buttons and make sure your fingers are on them only and don’t shift to other buttons - look at the display on the FRONT - click the + or – to adjust (hopefully I correctly memorized which finger is on the left button and which on the right) - click TOP alarm button for the minutes to flash - look at BACK to locate + or – buttons and make sure your fingers are on them only and don’t shift to other buttons - look at the FRONT of the display - click the + or – to adjust (hopefully I correctly memorized which finger is on the left button and which on the right) - click the button on TOP to set - WAIT 5 seconds for current time - click TOP alarm button to verify that I set correct alarm time - WAIT 5 seconds for the current time. Repeat to set the second alarm. In short, it is ANNOYING. The pros: (1) The display is pretty. (2) There is battery backup. (3) There are two alarms. (4) It is fairly loud. I thought it would be louder, but that’s a very subjective matter. ... show more

The 3 AAA batteries I put in the clock are brand new. Received the clock 48 hours ago. After a brief power outage overnight, I didn't think the time was kept. However, removing the power cord, the correct time was kept. Will use this for a month to see how it does. I enjoy the selection of colors of the LED. Purple is great. I can change to LED 3 levels of brightness and dark as well. There are five alarm volumes. Directions were easy to follow for set up and alarm. The snooze light on top is nice to have in a dark room, but you can turn it off as well. The clock itself does not run on batteries. Power adapter included. Same size as my Samsung phone. ... show more

    • Very loud, cute, easy to use
Color: Black+rgb
I have been using my clock for one month now. This clock grew on me, I really like it now. It's light plastic, but works great. Alarm is very loud, enough to wake me up which is not easy to do. I frequently change the color of the time for fun. I like the night light, but I need to keep it on red because the other colors are too bright for me. If that had a dimmer, it would be perfect. ... show more
